Outer Limits 4x4 Board

hi all,
just a quick question, my mate has just bought a wrangler with a 2 inch suspention lift and wants to put 31" muddies on it but he is not quite sure if they will scrub out in the guards. Does anyone know if they will?

31"s will fit a stock height TJ (Just).
Make sure his bump stops have been lowered a touch. If he's using stock rims he'll need to slightly adjust the steering stops to prevent rubbing on the lower ocntrol arms....that's it
